Approximate linearization, round a local operating point, is performed for the dynamic model of the VSC-HVDC transmission system. This local equilibrium consists of the present value of the state vector of the VSC-HVDC model and of the last value of the control input that was exerted on it, and is re-calculated at each time instant. To accomplish this linearization, Taylor series expansion and the computation of the associated Jacobian matrices are performed. The robustness of the control scheme allows to compensate for the modelling error which is due to truncation of higher order terms from the Taylor expansion. Next, an H-infinity feedback controller is designed. After solving an algebraic Riccati equation at each iteration of the control algorithm, the feedback gain is computed. Lyapunov stability analysis is used to prove that the control loop satisfies an H-infinity tracking performance criterion. This also indicates elevated robustness to model uncertainty and external perturbations. Moreover, under moderate conditions it is proven that the control loop is globally asymptotically stable.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115798211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main idea deals with the allocation of electric utilities' energy transport costs between output nodes of an electric network. The methodology proposed can be characterized as two-stage procedure. At the first stage, total energy transport costs are allocated between nodes (substations) and branches (power lines) proportionally to a contribution to the total electric utilities' energy transport costs of each element of a network. The results are obtained via energy flow model, which interconnects energy flows in nodes and branches. At the second stage, energy transmission & distribution costs are divided proportionally to the energy flows at each element of a network equivalent circuit, in order to quantify distribution costs for each consumer. As a result, it is possible to allocate distribution costs between nodes and branches, including electricity consumption nodes, in other words, to calculate energy-cost flows. Using the approach proposed, individual costs of electric energy transport to each particular consumption node can be easily assessed. As a result, individual transmission & distribution tariffs can be formed.","PeriodicalId":259750,"journal":{"name":"2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134602170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
